Attention - deficit / hyperactivity disorder (ADHD) is a psychiatric disorder that has neurobiological basis (Michanie, 2004).
People with ADHD have attention deficit, impulsivity and hyperactivity. It occurs on a percentage 5-7% of the school population and a ratio of 3 to 1 in favor of boys (Greek National Association of People with Attention Deficit Hyperactivity Disorder).
It is the current diagnostic label not only for children but also for adults who have significant problems with attention and excessive activity. Both children and adults with ADHD represent a rather heterogeneous population that displays significant variation in the degree of their symptoms, age of onset, cross-situational pervasiveness of those symptoms, and the extent to which other disorders occur in relation with ADHD (Barkley, 2014).
